small cut made for the needle does not usually need stitches. Pressure is put
on the needle site to stop any bleeding. A bandage is put on. A small metal
marker (clip) is usually placed in the area where the biopsy sample was taken.
This is done to locate the exact spot where the tissue sample was taken.
The metal marker will stay in your breast if you do not have cancer. You
will not be able to feel it, and it will not set off metal detectors. You can
still have an MRI safely. When you have mammograms in the future, the
radiologist will be able to see the metal marker.
This type of
breast biopsy takes about 60 minutes. But most of this time is needed for the
mammogram or MRI and finding the area for the biopsy.
A vacuum-assisted biopsy is
done by a radiologist or a surgeon. This method may be used for a core needle
biopsy or a stereotactic biopsy. The biopsy may be done while you sit or lie on
an examination table. Or you will lie on your stomach on a special table that
has an opening for your breast. A mammogram, ultrasound, or MRI is used to find
the exact site for the biopsy.
Your doctor numbs your breast with
a shot of local anesthetic. Once the area is numb, a small cut is made in your
skin. A hollow probe with a special tip is put into the breast. Tissue is
gently vacuumed into the probe. With this type of biopsy, the doctor can take
more than one sample without removing the probe.
